The affinity of lymphocyte 5'-nucleotidase (5NT) for its substrate adenosine monophosphate (AMP) was studied in Epstein-Barr virus immortalized B-lymphocyte clones from healthy controls and patients with primary hypogammaglobulinaemia. Km values for AMP for 5NT in most of the patient clones were found to be significantly increased compared to B-cell clones from normal subjects, whereas Vmax values were within the normal range.
